The flame should be very pale blue (almost invisible) for heating strongly. This is achieved by opening the air hole fully.
Keeping the air hole open allows for better and more efficient combustion by providing a sufficient oxygen supply. This ensures a hotter and more controlled flame, which is essential for heating objects evenly and quickly with a Bunsen burner.
When you have it in position, you cover up the back hole and the first front hole. That should make E. (At least if it is a normal one. I have no clue what it is for the extensions.)
The air hole should be fully open to ensure a safety flame. The air hole allows for proper ventilation and prevents the flame from becoming too large or unstable.
The bleed hole (or, "jiggle valve" as Ford sometimes calls it) should be in the upper twelve o'clock position.
because of heat genareted when drilling,matals tend to expand.hence the hole increases
I was funneling the liquids through a small hole.
There are three: Safety flame: The hole is closed. Orange flame. Not too hot, Blue flame: Hole half open. Almost invisible. Hot. Used for heating liquids, Roaring blue flame: Hole open. Very hot blue part inside lighter coloured part. Used for heating solids.
no if theres a hole , it broken . why is it over heating and how do you know its over heating, you cant look at it?
look under steering column by the key there should be a little hole . Just stick a awl in the hole and turn the key to on position and pull out.
When digging a hole, if you bend over you will be able to get the shovel deeper into the hole.
Make sure the hole in the bearing is aligned with the hole in the casting.
